our country's first Chinese standard intelligent urban train made a stunning appearance

Rail Transit Exhibition News On September 18, under the organization of CRRC, our country's first Chinese standard intelligent urban train with completely independent intellectual property rights made a stunning appearance in Qingdao. The train is innovatively built in accordance with the concept of "intelligence, digitalization, modularization, greening, and vehicle-ground integration", and will be used in the Jingxiong Express, marking our country's important new breakthrough in the field of urban rail transit equipment and the serialization of Chinese standard intelligent citiesTrains have been demonstrated and applied. Its advent has led our country to achieve a new upgrade of municipal train technology.

Chinese standards account for 88%

Comprehensive independent research and development of key core technologies

In order to build a pedigree technology and product platform for urban trains, and build Chinese standards, Chinese products and Chinese brands in the field of urban trains, CRRC took the lead in undertaking a series of major technical equipment research projects for the development and testing of Chinese standard intelligent urban trains. The train unveiled this time is one of the series of products under the series of Chinese standard intelligent urban train platforms, which is an urban D-type car with a speed of 200 kilometers per hour.

According to Zhu Jianhua, senior chief designer of CRRC Sifang Co., Ltd., as the first Chinese standard intelligent urban train, the car has built a Chinese standard system, and Chinese standards account for 88% of the technical standards adopted. Through independent research, the key core technologies of trains are fully autonomous. At the same time, the innovation is equipped with more than ten core technologies to achieve all-round upgrades in terms of intelligence, safety, comfort, energy saving and consumption reduction, and application economy.

Digital intelligence empowerment

The technical performance of the train has been upgraded

Smarter. The car integrates digital intelligence technology in all dimensions to create the strongest "intelligent brain" of urban trains, further improving the intelligence level of daily driving, application and maintenance.

The train runs at a speed of 200 kilometers per hour, using GoA4 fully autonomous driving technology, which is the country's first fully autonomous urban train with a speed of 200 kilometers per hour, and is also the world's fastest fully automatic rail vehicle.

In view of the problems of high speed, large station spacing, through-operation and mixed running of different lengths and lengths under fully automatic operation, the train adopts intelligent control technology of self-acceptance, self-learning and self-decision-making, and the driving failure rate is reduced by more than 95%.

For the first time, the hot standby switching technology is adopted, and when the vehicle control circuit fails, it can automatically switch to the standby system to achieve "non-stop" operation.

For the first time, it is equipped with a high-precision redundant perception system, which comprehensively and accurately perceives the status of key components such as the vehicle's running parts, traction, brakes, and doors through more than 2,900 monitoring points throughout the vehicle, and achieves "millisecond-level" response to common faults.

The use of digital twins, AI algorithms, etc. to build an advanced integrated intelligent operation and maintenance system has improved the ability of fault early warning and prediction, maintenance decision support, etc.

Safer. Upgrade the passive safety protection performance, add an anti-climb energy absorption device in the workshop, and adopt the multi-point collaborative technology of the front and workshop energy absorption structure, which doubles the collision energy absorption capacity of the whole vehicle and reaches a collision safety speed of 36km/h, which is the highest in the field of urban trains. Optimize the vehicle's anti-skid control to significantly reduce the braking distance in slippery road conditions such as rain, snow and ice.

More comfortable. Improve the ride experience in multiple dimensions. All-round sound insulation and noise reduction, through the control of equipment single-frequency noise and the application of porous resonance sound-absorbing materials, acoustic impedance gradient composite structures and other advanced noise reduction new materials and new technologies, the noise in the car is greatly reduced by 5dB.

The airtightness of the vehicle is more than twice as good as the standard requirements, effectively reducing the discomfort caused by pressure fluctuations in the car to passengers.

The cabin adopts intelligent control, from lighting brightness to air conditioning temperature, pressure change, broadcast volume, etc., can be adaptively and intelligently adjusted according to the external environment to create a more comfortable riding environment.

Greener. It adopts advanced aerodynamic design, uses variable section air diversion technology to improve the smoothness of the car body, and increases the covering structure of the running part to greatly reduce the air resistance of the train. In terms of lightweight, the front cab and equipment compartment are made of carbon fiber material, which is about 30% lighter than conventional materials 。 Through the use of low-resistance body, carbon fiber materials, permanent magnet traction, inverter air conditioning and other comprehensive energy-saving measures, the energy consumption of train operation is reduced by about 16%.

More economical. In order to improve the economy of operation, more than 200 spare parts and vulnerable and consumable parts are unified in the whole vehicle, and the repair process is optimized through component enhancement design, health intelligent assessment and other means, reducing the maintenance cost of the whole life cycle of the train.

Serve the Jingxiong Express

Helping the "Millennium Plan"

Urban trains are rail transit equipment that serves the fast, large-capacity, and bus-based passenger flow transportation between the central urban area of the city, the suburbs, and surrounding satellite cities. At present, with the continuous advancement of urbanization and metropolitan area construction in our country, urban trains are entering a period of accelerated development. The advent of China's standard intelligent urban train is of great significance for promoting the industrial scale and industry standardization of our country's municipal rail equipment, enhancing the core competitiveness of our country's municipal train equipment, and promoting the high-quality development of our country's municipal rail transit.

The Chinese standard intelligent urban train unveiled this time will be used to equip the Beijing-Xiong Express (Xiong'an New Area to Beijing Daxing International Airport Express). The train is designed with the idea of "indescribable, and the heart yearns for it"concept, the exterior of the vehicle integrates aerodynamicsWithModern aesthetic design, streamlined body using carbon fiber and other new materials, full of technology and futurism. The body is painted with the words "Sea of StarsThe theme is to integrate the twinkling brilliance of the stars and the rhythm of the surging waves, echoing the "City of the Future" of Xiong'an New Area ".

The Beijing-Xiong Express project is undertaken by Xiong'an New AreaBeijing's non-capital functions are an important transportation infrastructure. After the train is put into use, it will be connected with the Daxing Airport Line of the Beijing Metro to realize Xiong'an New Area30 minutes to Daxing International Airport and 60 minutes to Lize Business District will help build a one-hour metropolitan area in Beijing, relieve Beijing's non-capital functions, and serve the "Millennium Plan" The construction of Xiong'an New Area provides strong equipment support.
